Owls head coach Carvalhal was then engaged in a heated discussion with a steward as he attempted to take a seat just behind the dugout. More stewards and members of Wednesday’s backroom team were required to calm down the scuffle. Carvalhal eventually moved further back in the stand.

It is thought the altercation was noted in the referee’s report and will be submitted to the FA.

Greater Manchester Police confirmed they would not be taking action.

Carvalhal claimed the steward later apologised to him.

He said: “He apologised to me. It was a person with age. I must respect older persons but in that moment he acted really badly.”

Bolton boss Parkinson defended himself following the controversial flashpoint.

“It shows the passion of the game and how we all wanted to win,” he said. “Bannan made, for me, a very dangerous tackle right in front of us and I left the technical area by a couple of yards to have a go at him.

“Okay I maybe shouldn’t have done that but it’s a natural reaction.

“Carlos has ran from their dugout right across to get involved. After that, the ref sent us both to the stands and I wasn’t really concentrating on what was going on – obviously there was something because I could hear it – but I’ll leave that to you guys to sort out.”
